My present invention relates to a curler heater for drying the hair after it has been wound on hair curlers It is well known in the beauty trade that the drying of the curled hairto which has been applied a curling is alwayse tedious and slow process. Thehair, when it iscurled is usually treated with a curl setting solution that is of a heavy consistency and will only dry slowly. The; hair is wound on a curler element of metal andthen clamped in place It allowed to dry normally it will takea considerable length of time. Any means adapted for; speeding up this operation would undoubtedly make the curling of the human hair'greatly more desirable and conequipment for the drying of hair curls must, oi necessitih eef simple construc: tion, reedilyedaptahle to the hair being curled. It must be operable on a low voltage so that there will be eliminated as much as possible of the chance for electrical shock or other injury.

The preferable form-cisuch a device would also include the application of heat at a relativelylow temperature, but at the same time high enoughto speed; up the drying of the hair.

Its application should be to the center of a curl 7 so that all of the curl can be simultaneously treated while at the same time heat radiated over the exterior "of the curl can assist in carryingaway themoistiu etherein.

It is an important object oi my invention to provide a curl heater or curl dryer which may be electrically operated and which may be groped in a series that will be applied to a series of curls with great rapidity.

Another object of my invention has been the provision of a curl heater which may be associatedwith others of likenature in an electrical series; arrangement and the whole device operated from a-suppl-y source of approximately 110 volts of electricity. 7 v

A further obeet oi the invention is related to the'provision of a curl heater which is of extremely simple construction, readily adaptable to the presentmodes of electrical manufacture and including standard electrical equipment to insure their production at a lowcost.

Other objects and advantages of the invention will be apparent during the course of the following description in which I have shown a preferred embodiment of my invention.

Figure 16 is a perspective view of a conventional type of curler mechanism.

Rerernng toth drawin s, and especiallal F gure 1, the numeral 20. designates an extension cord or electrical conductor of the usual insulated or rubber-covered type. A pronged plug 2| is attached to one end 01 the cord and an interme'cliat or interline push thloiig h type switch 22 is also provided.

Distributor head 23 receives the ends of a. pluralityf of conductor wires 24, each of which leads to allieatr element designated by the numeral 25.

Inthe diagrammatic showing of the electrical circuit, which may be seen Figure 15, it will appear that from the two wires of the extension cord 20 is arranged in series the two 'wires of each of conductor cords 24. The electrical coils or? elements E are attached between the ends of the wires in conduit 14. The elements E are arranged together in the device in what is referred'to commonly as an electrical series arin the ends of the two compressible connector members 36 and 36' (see Figure 14) and the two ends of the lead-in wire 24 are also inserted in -moisture which may be in the curl. At the same time the body 26 enclosing the heater element will also h at the exterior portion of the curl ad jacent which it lies. By rotary adjustment of the heater device with relation to the curl, the exterior of the curl may be progressively heated throughout its entire circumference. It will be apparent, however, that the heat radiating from the body will probably be considerably lower than the heat radiating from the bar 36, due to the'insulation provided in the body 26. I

It is my intention to construct the heater unit and'the electrical element therein of extremely the opposite endsof the elements 36 and To eliminate the chance of arcing or the shortcircuiting between the member and themember 36, I employ an insulation bushing 38 which en- 7 lightweight materialior the purpose of providing a, unit which will not overly tax' the user by burdening the hair. By properly suspending the distributing head 23 somewhat above the head of the wearer the majority of the weight of the conductor wire 2:3 can also be relieved from the circles the member 36' and separatesit from the member 36., n 7

To prevent separation of the ends of the two wires forming the conduit 24 I pass the tie member 69 around the conductor wire 2 and secure it tightly in place.

The bar of the U-shaped conductorrod 32 passes through a notch in the'end of the body member 26 and a cap 62 fits therein and closes that end of the body. A cross-pin M is useful in retaining the cap d2 in position. I

The foregoing description and the'accompanying drawings are believed to clearly disclose a preferred embodiment of my invention, but it will be understood that this'disclosure is merely *illustrative and that such changes in the invention may be made as are fairly within the scope and spirit of the following claims.

In Figures 3, 4-, and 16, I have illustrated a 7 conventional type of curler member which is commonly used in curlingthe hair, This member forms no part of this application, but is.

merely illustrated for thepurposes of explaining the operation of my heater or dryer mechanism. The curler may consist in this case of a perforate tube 46 which has pivoted to one end a segmental member 48, also perforate and a U-shaped wire member 59. Ordinarilyv a rubber ball 52 snaps over the open end of the tubular member 46 and retains the bar longitudinally along the sides of the tubular member. An end of the hair to be curled is inserted between the tubular member and the member 43, The clamp member 48 is' rmlyclamped down against the tube by pressure being applied to close the clamp on the tube. The-hairisthen wound around the portion of the tube lfiwhich is'eXposed, as well as around the arcuate'or segmental member 48until a sufficient amount has'been wound thereon to form a proper curlf-The hair coiled on the tube or curler is indicated by numeral 41. f V Whenthe curl'is properly wound on the curler, the retainer member. 59 is clamped into place and the drying step of the curling process may begin.

Inorder to facilitate the drying of the'h'air, I insert the bar 32 of my curlerinto the opening in the center of the tube 55., Forea'ch curl that has been formed on a'curler, a heater bar or dryerinember will be provided and inserted into the tube. The electrical plug 2! is'then'inserted into a suitable outlet receptaclafthe'switch 22 closed to, energize the circuit and the 'elements- E within the body 26 will begin to heat. The elements 1E will be only of such capacity as will heat the "bar 34 to a sufiicient' degree to "speed the dryingof the hair,"but at the same time will not be so hot as to burnthe skin upon contact.

The bar S S when it is heated and within the centerof the tube lfiv of the curler, will cause heat to radiate throughout the interior of the our to materially assist in the dispersion of the Iclaim: 7 1, In a curler heater of the type wherein an i electric extension cord having connector means for engagement within an outlet receptacle and also having a switch'for opening and closing an electrical circuit is also provided with a distrlbutor head and a plurality of double-wire electrical conductor cords associated with said distributor head and electrically joined together in a series arrangement, a heater on each cord comprising a'tubular casing of electrically nonconductive material having means for receiving an endof one of saiddouble-wire electricalcords, said casing also formed with an open end having a lateral notch, a coiled electrical element within said casing in series with the wires of said conductor cord, anelectrical bushing in the coil of said element, a u shaped conductor barfhaving one leg disposed in'said encircled bushing and the other leg disposed outside of said casing parallel to the longitudinal axi thereof, the cross position of said U-shaped bar engaging in the notch in the casing and a plug closing the open end of said casing, and having'means for engaging over a portion of the U-shaped bar as it passes through the notch in the casing.
